Weathering Steel Multi-Girder Rating

Started the new job last Monday and jumped on a rating right away.

The rating is part of a contract for RIDOT and is a steel multi-grider system with a composite deck. The bridge is located in downtown providence and spans 102 feet over the Woonasquatucket River.

First I calculated the dead loads and live load factors and then I moved onto setting up the BRASS-Girder input file.

The bridge had for bays with different types for utilites which made selecting which girders to rate a little more difficult.

Its been over a year since I last used BRASS so I had to shake out some of the rust (lots of errors and looking up most of the input order). After about three tries I was finally able to get it to run correctly.
